How Our Frequency Distribution Calculator Works
The calculator expands your value-frequency data into a full set, then computes mean, median, mode, and range. You can analyze discrete, grouped, and classed datasets instantly. It's ideal for stats, probability, and practical analytics.
Calculation Steps
Mean = Σ(value × frequency) / ΣfrequencyMedian = value at middle position (expanded data)Mode = most frequent value(s)Range = max − min (expanded data)For grouped data, use class midpoints. The calculator will show a complete frequency table and breakdown.
Shows each value, frequency, and computed statistic.

Data Table:
- Value: 1 – Frequency: 1
- Value: 2 – Frequency: 2
- Value: 5 – Frequency: 1
Calculation Steps:
- Mean = (1×1 + 2×2 + 5×1) / (1+2+1) = 10/4 = 2.5
- Median = (middle) = 2
- Mode = 2 (highest frequency)
- Range = 5 - 1 = 4
Result: Mean = 2.5, Median = 2, Mode = 2, Range = 4
